Question

A signal is band limited to 2 KHz. It is sampled, quantized in amplitude, and line coded using binary raised cosine pulses. The maximum quantization error cannot be greater than 1% of the peak signal amplitude. The sampling rate must be 25% above the Nyquist rate. a. Determine L, the minimum number of quantization levels. b. What the essential transmission bandwidth if raised cosine pulses are used with a roll-off factor of a = 0.2? c. What is the essential transmission bandwidth if sinc(-) pulses are used? d. What is the essential transmission BW if NRZ rect(-) pulses are put to use?
